Heart-related discomfort can spread to:
the arm (especially the left arm)
the back
the jaw
the neck or shoulder
It might feel like pressure, numbness, or even a strange ache.
6. Dizziness or Lightheadedness
Feeling like you might faint — especially when standing up — can happen when the heart isn’t supplying enough blood to the brain.
7. Sudden Cold Sweats
Cold sweats that appear without reason (like heat or exercise) may be a stress signal from the body that something isn’t right.
